Old Cistern Map

The cistern is a low complex of brick vaults, knee-deep channels, pressure doors, and maintenance ledges. Sound carries. When the PCs make noise in one chamber, describe ripples and answering knocks from the next.

Drain stair: safe entrance, slick but visible from the market grate.
Sluice hall: location of the Pressure Sluice trap.
Valve chamber: old brass key is wedged in the mechanism.
Lantern well: final encounter and relighting point.
